Brooke Elizabeth White was born in Phoenix, Arizona, and raised in nearby Mesa, with three younger siblings (Katie, Tyler, and Quinn) and her parents, Brad and Kaylene. She also has family members in Nova Scotia, Canada.[5]

White started singing at 16, when she tried out for the high school musical, Meet Me in St. Louis, and earned the lead role.[5] White was graduated from Heritage Academy high school in 2001. She, at one time, attended beauty school, and described herself as a "beauty school dropout,"[5] and shared on Idol that she started doing hair when she was eleven years old. White moved to Los Angeles, California when she was nineteen years old where she attended the Musicians Institute for three months and then spent the next four years honing her craft as a singer-songwriter recording in the studio and performing in the clubs of Hollywood, California under the guidance of Tim Simms. White also spent a year as a nanny for twin baby girls. During her elimination video on American Idol, White stated "It's probably not a secret that I struggled with my own confidence but I'm stronger than I thought I was and that's a great thing to get out of this." White currently resides in Van Nuys, California, with her husband, David Ray.[6] White is a member of The Church of Jesus Christ of Latter-day Saints. White and her husband have one daughter, London, born on May 24, 2012 in Los Angeles, California.[7] In February 2016, White announced that she was expecting a baby boy.[8] On September 3, 2016, they welcomed son, Sonny John Ray.[9]

White auditioned for American Idol, in Philadelphia, where she sang "Like a Star" and received positive reviews from all of the judges. During her audition, she admitted to never having seen an R-rated movie, which prompted Cowell to state that he could "bring her over to the dark side." During Hollywood week, White performed "Beautiful", by Carole King, and accompanied herself on piano. After that performance, judges commented that White reminded them of a young Carly Simon or Carole King.

During the 1970s theme week, while White performed "You're So Vain", by Carly Simon, she stared at Simon Cowell. It caught the judges' attention and received good reviews from them. White performed an acoustic version of "Love Is a Battlefield" by Pat Benatar, in the next week to good reviews, as well. During the Lennon–McCartney week, she performed "Let It Be", a classic song by The Beatles. Randy Jackson said it was a very heartfelt performance and Simon Cowell said that it was believable and one of the best of the night and that he thought that Brooke had picked good song choices in the past three weeks.

Andrew Lloyd Webber, who served as guest mentor for a show, based on his own music, was particularly impressed by White and predicted a big night for her.[11] However, three lines into her performance of "You Must Love Me", White apologized, stopped the band and restarted the song from the beginning. She later explained, "I lost the lyric." Simon Cowell stated that he would have done the same thing, had he been in her situation. It was the first time in the show's history that a contestant restarted a performance from a point so far into the song. (White had previously restarted "Every Breath You Take", after a single odd note.) Despite this, she was the third contestant to be named safe on the subsequent results show, while Carly Smithson went home.

When White performed "I'm a Believer" and "I Am...I Said", during Neil Diamond week, she personalized the latter, at Diamond's own suggestion, by changing the lyrics from "I'm New York City born and raised" to "I'm Arizona born and raised."

In an interview with Entertainment Weekly, White stated that she will continue to focus on recording and that she received a call from Carly Simon. When asked about returning as a nanny of the twins, White said that the family joked that they would give her a raise, if she went back, and she said that she did not mind babysitting every once in a while.[12] After White's elimination, she made appearances on The Tonight Show with Jay Leno on May 1, 2008,[13]Live with Regis and Kelly and The Ellen DeGeneres Show on May 5, 2008,[14][15]The Morning Show with Mike & Juliet on May 6, 2008,[16]Good Day L.A. and Access Hollywood.[17] She also filmed an appearance on MTV's Total Request Live on May 6, 2008.[18] While on The Ellen DeGeneres Show, Ellen DeGeneres cut White's husband David's hair, since he had vowed not to cut it until Brooke was eliminated from Idol.[15][19] She performed "You're So Vain" on The Ellen DeGeneres Show, Live with Regis and Kelly, The Morning Show with Mike & Juliet and Access Hollywood. White shot a video for the VH1 TV show Best Week Ever, called "Brooke White Starts And Stops The Classics". In the video, White mocks herself and starts and stops while singing some classic songs. White returned to the Idol stage for the season finale and performed, along with the other Top 12 contestants. She also sang "Teach Your Children", with Graham Nash. White filmed a commercial with fellow finalists, Syesha Mercado and Carly Smithson, she has become the spokeswoman for "Save The World Summer", a campaign launched by Malaria No More and Idol Gives Back. White stated in an interview that she would not sign a record deal until the tour finished. "There are definitely certain things that I have to abide with in my American Idol contract. I won't sign anything, until three months after the show is over. That doesn't mean that I'm not looking ahead and preparing for the future. The point of doing the show was not just to be on TV but to launch into a real career."[20] White completed the American Idols LIVE! Tour 2008, which ran from July 1, 2008, to September 13, 2008. She performed "Let It Be" by the Beatles, "1234" by Feist and "Yellow" by Coldplay (which is also included on White's debut album Songs From the Attic).

The performance was free to the public; however, donations to Malaria No More were accepted. The event was sponsored by the Mesa Convention Center, Milano Music Center, and Malaria No More.
